A Cenepred risk assessment has flagged 116 hydroelectric plants operating across Peru as sitting at high or very high danger from huaicos, landslides, and floods during the upcoming 2027 summer season — a scenario that, if it unfolds, threatens plants whose reservoir supply comes from the same Andean highland terrain where El Niño historically concentrates drought, according to the national mining and energy society and projections cited by Gestión.
That threat is not theoretical. Peru's 191 hydroelectric plants supply more than half of all electricity fed into the national grid, and every major El Niño event on record has sent spot-market energy prices soaring, squeezing businesses that have no rate protection.
